MORPHOLOGICAL POWDER ANALYSIS

The powder morphology is analysed at a micron-level thanks to Scanning Electron Microscope (SEM), combined to Energy Dispersive X-Ray device (EDX) for a complete quantitative-qualitative analysis and purity assessment.
GRANULOMETRIC ANALYSIS

The granulometer assesses the dimensional properties of the particles. The size of each grain is compared to the analysis sample and must fall within the given tolerance range.
FINENESS TEST

The spectrophotometric analysis reveals the elemental composition of each sample and, in so doing, allows the accurate certification of the alloy fineness.
FIRE ASSAY

The fire assay method is considered compliant with the standard to ensure the most accurate fineness determination of jewels.
SURFACE ROUGHNESS ANALYSIS

Measuring and assessing the surface micro-irregularities of the printed pieces, at a X thousandth of a micron accuracy level.

Quality Control: Tomography applied to titanium objects

Thanks to the tomographic analysis of the objects we print in titanium, we can compare the dimensions of the customer's STL file with those of the real printed piece, with greater precision than measurements made by hand with the caliper. We can also see defects such as porosity within the part itself, which would otherwise be invisible to the naked eye.

Six Metals

Different solutions

PLATINUM 950‰

Alloyed at 950‰, printed Platinum pieces emphasize the advantages of the technique.
YELLOW GOLD 750‰

Alloyed at 750‰, the pieces comply with standard 2N or 3N colours, according to EN2864.
RED GOLD 750‰

Alloyed at 750‰, the intense shade of the printed red Gold jewels can be defined as 5N+.
WHITE GOLD 750‰

Alloyed at 750‰, Ni-free white Gold with a 130‰ Palladium content.
TITANIUM

Grade 1 Titanium, with an excellent resistance to corrosion, is particularly suitable for obtaining extremely light pieces.
